Beans configuration error

  • 772

Hi, I have the following code in the application-context of my project.

bean id="bean" class="ej.tutorial.spring.model.MyBean" />
<bean id="beanSvc" class="ej.tutorial.spring.model.OtherBean">
<property name="mBean" ref="bean"/>
</bean>

The classes are the following:

public class MyBean {

private int valor;
private String msg;

public MyBean(){

}

public MyBean(int valor,String msg){
    this.valor = valor;
    this.msg = msg;
}

public int getValor() {
    return valor;
}

public void setValor(int valor) {
    this.valor = valor;
}

public String getMsg() {
    return msg;
}

public void setMsg(String msg) {
    this.msg = msg;
   }
}

OtherBean class:

public class OtherBean {

private MyBean mBean;

public OtherBean(){

}

public OtherBean(MyBean bean){
    this.mBean = bean;
}

public MyBean getmBean() {
    return mBean;
}

public void setmBean(MyBean mBean) {
    this.mBean = mBean;
    }

}

Well, the application-context gives me an error. The error is the following.

No setter found for property 'mBean' in class 'ej.tutorial.spring.model.OtherBean

The truth is that I can't find a logical explanation for it since the setter of the mBean attribute is defined in the OtherBean class.

  1. In your applicationContex.xmldefine your bean and its property:

    <bean id="myBean" class="ej.tutorial.spring.model.OtherBean">
        <property name="mBean" >
            <ref local="mBean"/>
       </property>
</bean>

  <bean id="mBean" class="ej.tutorial.spring.model.MyBean">
  </bean>

    For properties, the getters and setters are named like:

    • get/is/set1 , followed by

    • property name, with the first letter capitalized .

    So, for the property mBean, you should define the methods getMBean()and setMBean(MBean mBean).

    1 In theory, if the property is of type boolean, the getter should start with isinstead of get, but I don't know of any framework that doesn't find the getter if you write it with get.

    Note that if the property is Boolean, then it must be used get.
